1. Looks like you’re trying to build a breakout box, you say this comes out of a 600? I have a 600SEL but don’t see this anywhere, but I did see this on my 95 C220 the main ECU.
2. Try Ebay also the junk yard.
3. Pay attention to the pin-outs when you get all the parts ready for the project. It’s not just easy as 1 to 1. Last thing you want to do is burn your ECU
